Question

What is the excess pressure in side a soap solution of radius 5.00mm, given that the surface tension of soap solution at the temperature is?

Answer 1

100mm in side the soap solution in the temperature

Answer 2

It has no component perpendicular to the horizontal surface. As a result, there is no pressure difference between the liquid side and the vapour side. ... Thus, there is always an excess of pressure on the concave side of a curved liquid surface over the pressure on its convex side due to surface tension.
